The present invention relates to a kind of method and apparatus for running for motor vehicle brakes and it is related to a kind of braking system
System.
Background technology
The brake request of the driver of vehicle is responded, the brake for vehicle is exported in the case where using brakes
Brake pressure.The brakes includes electronically controlled adjustment element for this.Pneumatic backup path is set to be used as to electronics
The stand-by provision of the adjustment element of control.
The content of the invention
The task of the present invention is to realize a kind of to be used to run the improved method of for motor vehicle brakes and improved set
It is standby and realize a kind of improved brakes.
The task by according to independent claims be used for run for motor vehicle brakes method and apparatus and
Brakes solves.
Current technical scheme is based on following cognitions：In the case where having identified failure, adjusted in adjustment element, such as pressure
Save modular form adjustment element in provide brake pressure when, with not Qiang ZhiyaoQiung lasting no current or electric-type passively cut
Change adjustment element and brake pressure is exported by pneumatic backup path without Qiang ZhiyaoQiung.Thus, it is possible to pass through pneumatic standby road
Footpath is drawn：Systematic function in stand-by state ensures the security of minimum level.The adjustment element is switched to no current
State in and from there through pneumatic stand-by provision provide brake pressure, this is according to fault type but not always optimizes
Strategy, although because not keeping the level of security that may be higher in malfunction using electricity regulation at this.According to failure
Type can by electric-type provide brake pressure and realize more preferable systematic function.This be particularly suitable for use in can also be related to it is pneumatic standby
The malfunction in path.Can be in the case of the pressure regulation device failure for motor vehicle braking system in fact by following manner
The improvement of existing systematic function：Pneumatic backup path is not switched to forcibly when identifying failure.
Method for running for motor vehicle brakes, wherein, the brakes has electronics adjusting apparatus gentle
Dynamic adjusting apparatus, the electronics adjusting apparatus are used for the brake pressure that the brake for vehicle is exported in normal operation mode,
The pneumatic adjusting device is used to export brake pressure in standby operation mode, the described method comprises the following steps：
If failure is related to following failures, pneumatic adjusting device is switched to by the electronics adjusting apparatus with the failure and drawn
Rising improves brake pressure output, then the fault-signal for the failure for showing electronics adjusting apparatus is categorized as to the event of Fisrt fault classification
Hinder signal；With
If the fault-signal is the fault-signal of Fisrt fault classification, pneumatic tune is switched to by electronics adjusting apparatus
Engagement positions, to export brake pressure in the case where using the pneumatic adjusting device.
Vehicle can be related to the related vehicle of road, more particularly to commercial car.Brake pressure can be used in activate brake,
Such as the running brake of vehicle.Brake pressure can be defeated in response to the driver of vehicle or the brake request of accessory system
Go out.Electronics adjusting apparatus can be configured to export brake pressure with controlling by electric control signal.Pneumatic adjusting device being capable of structure
Make for exporting brake pressure with controlling by pneumatic control pressure.Electronics adjusting apparatus and pneumatic adjusting device can be using only
It is implemented in the case of vertical element or the element being at least partly used in conjunction with.Such as relay valve can be set, the relay valve energy
It is enough to be used and in pneumatic adjusting device operation by the pneumatic tune by the electronics adjusting apparatus in the operation of electronics adjusting apparatus
Engagement positions use, and are therefore not only able to be considered as the part of electronics adjusting apparatus and can be considered as pneumatic adjusting device
Part.If thus it is expected improve systematic function, this method can realize be switched to by normal operation mode it is standby
In pattern.
If for example, the failure is traced back to the reason for electricity in electronics adjusting apparatus, the fault-signal point
Class is the fault-signal of Fisrt fault classification.If failure shows have electricity short in the electric line for being associated with electronics adjusting apparatus
Road, then the fault-signal can also be categorized as the fault-signal of Fisrt fault classification.Therefore, so-called " 1 class " failure not only can
Enough it is related to short circuit, and all kinds of failures that can be substantially identified in electricity is adjusted can be related to.In addition to suitable for short circuit, this
Suitable for the open circuit of such as electric line, the output stage of damage, the sensor failure band, the electronic component damaged；Suitable for depositing
Reservoir failure, such as RAM/ROM/EEPROM failures；Software suitable for collapse etc..Thus in the case of such failure
It usually can draw：Systematic function can be improved by using pneumatic backup path.
In classifying step, if the failure is related to following failures, by with the failure in the case of the failure
Electronics adjusting apparatus, which is switched to pneumatic adjusting device and do not caused, improves brake pressure output, then the fault-signal is categorized as into the
The fault-signal of two fault categories.In this case, the step of this method can include keeping using electronics adjusting apparatus, with
Just if fault-signal is the fault-signal of the second fault category, then system is continued to output in the case where using electronics adjusting apparatus
Dynamic pressure.Therefore, if can not thus it is expected to improve or even deteriorate systematic function, can avoid by normal operation mode
It is switched in standby operation mode.
Correspondingly in classifying step, if the failure is related to following failures, in the case of the failure do not know by
Electronics adjusting apparatus with the failure is switched to whether pneumatic adjusting device causes improvement brake pressure output, then the failure
Modulation recognition is the fault-signal of the 3rd fault category.In this case, this method can include at least temporarily with by electronics
Adjusting apparatus is switched to the step of pneumatic adjusting device, if so as to the fault-signal that fault-signal is the 3rd classification, at least
Brake pressure is provisionally exported in the case where using pneumatic adjusting device.This can be realized in a manner of test by normal operation
Pattern switching is into standby mode.It can test by this way, whether such switching causes improvement systematic function.If
Such case, then it can keep the switching.Otherwise, it can return and be switched in normal operation mode.
For example, in classifying step, if the failure is related to following failures, the failure is based on being associated with electronics tune
Suspicious pressure tendency in the pneumatic pipeline of engagement positions, then fault-signal be categorized as the fault-signal of the 3rd fault category.
Under such circumstances, it often can not reliably predict and be switched to whether pneumatic backup path causes improvement systematic function.
This method can include identification step, can be identified in identification step：By with faulty electronics adjusting apparatus
It is switched to pneumatic adjusting device and causes improvement brake pressure output, or by being switched to pneumatically with faulty electronics adjusting apparatus
Adjusting apparatus, which does not cause, improves brake pressure output.In addition, this method can include being adjusted by pneumatic adjusting device to electronics
The return switch step of device, if to be identified in identification step by being switched to gas with faulty electronics adjusting apparatus
Dynamic adjusting apparatus, which does not cause, improves brake pressure output, then exports brake pressure in the case where using electronics adjusting apparatus.
By this way, if drawing standby operation mode relative to normal operation mould after being switched to standby operation mode in test
Formula does not improve or even deteriorated, then can return to normal operation mode.
For example, in identification step, by first during brake pressure is exported in the case of using electronics adjusting apparatus
Systematic function is compared with the second system performance during brake pressure is exported in the case of using pneumatic adjusting device.It is logical
Cross and compare two systems performance and can identify, which of two kinds of operational modes (i.e. normal operation mode or standby operation mode)
Cause more preferable systematic function.
Such as systematic function can by the pressure being associated with the pneumatic pipeline of brake, by the deceleration of vehicle and
Additionally or alternatively defined by being associated with the wheel-slip of brake.According to an embodiment, not only using involved
And wheel-slip, and use slippage between the wheel of vehicle and another wheel being related to as evaluation criterion because
Slippage can be measured particularly simply and convincing.In addition, systematic function can be defined by manipulating the source of signal.Behaviour
The source of signal is controlled it will be appreciated that being driver or accessory system.Standby pressure is not provided in this accessory system.
This method can include the return switch step by pneumatic adjusting device to electronics adjusting apparatus, to use electricity
Brake pressure is exported in the case of sub- adjusting apparatus.In addition, this method can include identification step, can in the identification step
Identification improves brake pressure output by whether the return switching of pneumatic adjusting device to electronics adjusting apparatus causes.With this side
Formula, for example, can be at regular intervals mode or respond the mode of particular event and check whether by standby operation mode still
Than more preferable systematic function can be realized by returning to normal operation mode.When determining operational mode also it can be considered that, be
Driver or accessory system claim.It can not be exported and pressed by pneumatic stand-by provision when being claimed by accessory system

Embodiment is described in more detail below according to accompanying drawing before.
After identification is out of order in adjustment element 102, the known systematic function in standby regulation changes only in failure
When kind, adjustment element 102 is just switched in standby mode 403.This generally for example can be bright in the failure (short circuit, broken string) of electricity
Really determine.The failure cause suspicious reaction of pressure sensor value (such as after electromagnetism valve events) can not clearly determined
Fault Identification in, " tentatively " switching 407 is determined by standby pressure adjustment element 102 to brake pressure 330 first
In pattern, however, sensing device 344 continues to run with, so that observing system responds.Determined by the systematic function for comparing two patterns
It is fixed：It is to continue with being maintained in standby operation or returns and is switched to electric regulation.
If electricity regulation is proved to be favourable, then continues electricity regulation.Brake pressure especially in electric-type is provided
Other function, such as ABS, ESP, AEBS (brake hard auxiliary) are able to maintain that when 330.
It is the standard that electricity is adjusted or standby regulation is more favourable as evaluation, such as desired brake pressure can be referred to
Relative to the difference or ratio of the brake pressure 330 actually reached respectively in two patterns.Also edge after the handover can be used
The gradient of the pressure change in desired direction is as standard.By comparing in electricity operation and the pressure information in standby operation
Determine：Which kind of pattern is more favourable pattern to systematic function.
As the other standard determined for this, it can use reached deceleration or corresponding wheel reached
Skid or corresponding wheel is compared to the slippage that other wheels are reached.
Because systematic function changes with the change in environmental condition, advantageously, periodically repeat following
Test：Which operational mode obtains more favourable systematic function.Repeat standard can for example be to determine time, output pressure
Pressure threshold, the pressure tendency of output pressure, the pressure threshold of bleed pressure, the pressure tendency of bleed pressure.
As already implemented, other function, such as ABS are able to maintain that when brake pressure in electric-type is provided.Such as
Fruit can not reliably determine that electric-type backup path or pneumatic backup path are more to have to systematic function when identification is out of order
Profit modification, then this can be asked for by comparing the systematic function of two patterns.
When Fault Identification clearly can not determine failure cause, adjustment element 100 be switched to brake pressure pass through it is standby
In the pattern that pressure determines, however, further pressure information known to system.By comparing in electric-type operation and in standby operation
Pressure information determine：Which pattern is the pattern more favourable to systematic function.
Because systematic function changes with the change in environmental condition, advantageously, periodically repeat following
Test：Which operation type obtains more favourable systematic function.Repeat standard can for example be to determine time, output pressure
Pressure threshold, the pressure tendency of output pressure, the pressure threshold of bleed pressure, the pressure tendency of bleed pressure.
For assessment of system performance, the comparison of the pressure of desired pressure and physical presence can be referred to or can be referred to
Difference between two patterns.
Can be the deceleration that vehicle 300 or wheel 120 can be realized to another standard for being switched to other patterns.If energy
The deceleration enough realized is reduced to below the value legally required, then is switched to another pattern.Slow down if existed after the handover
Improvement, then keep the pattern, otherwise, again return switch the pattern.
Another embodiment can be that standby mode is kept after once test.
Deceleration can be caused by the brake pressure 330 realized or by by observation wheel velocity or observation sensor
(acceleration, GPS ...) 344 measures vehicle deceleration to determine.
Embodiment described is exemplarily only selected and can be mutually combined.
